U.S. Secretary of Education Betsy DeVos, who has spent decades advocating for private school vouchers and charter schools, came to Washington with one item at the top of her agenda: to push for a new federal school choice initiative.

Her vision is running into trouble on Capitol Hill, where lawmakers in both chambers have failed to fund either of the school choice proposals in the president’s budget. And it’s looking less and less likely that the White House will push to include a federal tax credit scholarship program in a sweeping tax overhaul package that’s slated to be unveiled soon.

So where does that leave the secretary? She is not giving up, she said in a wide-ranging interview with Education Week last week. And she wants to make sure the administration pursues the best possible school choice policy.
